The tech news site notes that the March 11 quake "has caused power outages and damaged production facilities." Among those affected: Toshiba, which produces 35% of global NAND supply. The report also says that Toshiba suffered a brief production outside a few days before the quake in an incident not yet officially disclosed by the company.

DigiTimes says the company's facility in Tokkaichi suffered little damage; SanDisk, which partners with Toshiba in some NAND production disclosed that their joint venture plants were down for a short period but back up on Friday.

Meanwhile, DigiTimes in a separate story reports that the quake could disrupt suppliers of silicon wafers. The site says that the main silicon wafer plant operated by Shin-Etsu Handotai , in Skirikawa, has shut down due to a lack of electricity. That plant, the story reports, accounts for 22% of global wafer share.
